Exception: Unable to set the pixel format.

I don't experience crashes at start, but I do get an Exception if I'm switching between windowed and FullScfeen mode and changing the Antialiasing setting at the same time. If I change these separately there is no exception raised.
So I assume the bug lies in code used to reinitialize renderer. My guess is that at certain point during this process there is no valid handle either to game window (I noticed it gets recreated every time) or there is no valid handle to the underlying API (OpenGL or DirectX). The later would also cause such exceptions on computers which are automatically switching between integrated and dedicated graphics card since rendering handles get recreated.
Here is part of the long indicating what is happening at the time:
